I seem to remember a TU154M (?) #2 engine fire after take off - attributed to start valve open after start - starter continued to run - overheated - and caught fire at some point - aircraft crashed and was destroyed.
Oh yes, and people were killed.
So, if we get a start valve not closed type message after start, lets shut it down then shall we.
It may be your mate on the headset who gets showered with red hot bits of starter turbine as well.
